Thanks for the tg-admin output. The TurboJson installation was ok.
But I think I found the problem. It seems you quickstarted the project for SQLObject instead of SQLAlchemy (which is the default now), right?
It seems in this case the quickstarted config/app.cfg file has the setting identity.provider = 'sqlobject' commented out and therefore, the sqlalchemy provider is activated.
Can you verify this and check what happens if you uncomment the identity.provider setting?
I will fix the quickstart templates so that the identity.provider is set properly and also try to get a better error message.
